Justin Bieber works out plea deal in ATV assault case; only has to pay a $750 fine

Justin Bieber has pleaded guilty to simple assault and careless driving stemming from an ATV incident involving ex-girlfriend Selena Gomez and two paparazzi.

The "Baby" singer appeared via video in a Stratford, Ontario, Canada, courthouse, according to the Toronto Star and TMZ, to enter the plea in a deal reportedly worked out by his legal team.

Bieber's reps did not immediately respond to the Los Angeles Times' requests for comment.

The 21-year-old received an "absolute discharge" on the assault charge and only has to pay a $750 fine for the careless driving charge, the Toronto Star said. He faces neither jail time nor probation.

A judge warned the pop star that the lesson in this case was to "think before you act in the future."

"Everybody in life, no matter who they are, encounters difficult and disappointing and surprising situations," Justice Kathryn McKerlie said. "And part of maturing, of course, is to make sure that when you encounter those situations that you proceed calmly and think before you act."
